- Quick guide
- </h2>
- <p>
- Set up two virtual computers - SimpleArbiterDhcp and FileServer.
- </p>
- <p>
- Make sure that the directory /srv/nfs/ERLbbBrT on FileServer is accessible
- over NFS and over SMB under the sharename urania-03.
- Set the SMB server name to zarptica-32.
- </p>
- <p>
- SimpleArbiterDhcp should have write access to /srv/nfs/ERLbbBrT over NFS.
- </p>

- <li>
- <span id="code">
- apt-get update
- </span>
- </li>
- <li>
- <span id="code">
- apt-get install isc-dhcp-server

- The server will not start (error
- <span id="code">
- Starting ISC DHCP server: dhcpdcheck syslog for diagnostics. ... failed!</span>)
- , configure 3 files:
- <ul>
- <li>
- In /etc/network/interfaces set static IP for eth1 on which the DHCP server will be running,
- e.g.:
- <p id="code">
- auto eth1<br>
- iface eth1 inet static<br>
- address 192.168.1.10<br>
- netmask 255.255.255.0<br>
- network 192.168.1.0<br>
- broadcast 192.168.1.255<br>
- </p>
- </li>
- <li>
- In /etc/default/isc-dhcp-server:
- <p id="code">
- INTERFACES="eth1"
- </p>
- </li>
- <li>
- In /etc/dhcp/dhcpd.conf configure the subnet properties,
- e.g.:
- <p id="code">
- authoritative;<br>
- default-lease-time 600;<br>
- max-lease-time 7200;<br>
- <br>

- Set up a NFS server
- <ol>
- <li>
- apt-get install nfs-kernel-server

- <li>
- Determine the rules in /etc/exports, e.g.:
- <p id="code">
- #privileges for SimpleArbiterDhcp<br>
- /srv/nfs/ERLbbBrT 192.168.1.180(rw,sync,insecure)<br>
- /srv/nfs/ERLbbBrT 192.168.1.0/24(ro,sync,insecure)<br>
- </p>
- </li>
- <li>
- Change the owner of the directory and files in it:
- <span id="code">
- chown student /srv/nfs/ERLbbBrT
- </span>
- and similarly for all the files in shared directory. The owner should not be root.
- </li>
- <li>
- Run command
- <span id="code">exportfs -rv</span>

- <ol>
- <li>
- <span id="code">
